Description

La présente invention concerne un dispositif de fixation d'un objet sur un mur de bâtiment. Cette invention a, également, trait à un système de montage d'un garde corps sur un mur, ce système comportant un dispositif de fixation tel que susmentionné.The present invention relates to a device for fixing an object on a building wall. This invention also relates to a system for mounting a railing on a wall, this system comprising a fastening device as mentioned above.

Cette invention concerne le domaine du bâtiment et trouvera une utilité toute particulière lorsqu'il s'agit de fixer, de manière temporaire, un garde corps sur un mur préfabriqué.This invention relates to the field of the building and will find a particular use when it is a question of fixing, temporarily, a railing on a prefabricated wall.

On connaît, d'ores et déjà, des dispositifs conçus pour permettre la fixation, sur un mur préfabriqué, d'un objet, plus particulièrement constitué par un garde corps ou par une console conçue pour recevoir un tel garde corps. Un tel dispositif adopte la forme d'un ensemble constitué par une cheville ou analogue et par une vis, vissée à l'intérieur d'une telle cheville, ceci pour la fixation d'un tel objet sur le mur. Un dispositif connu est décrit dans FR 2 913039 .Already known, devices designed to allow the attachment, on a prefabricated wall, an object, more particularly constituted by a railing or a console designed to receive such a railing. Such a device adopts the form of an assembly consisting of an anchor or the like and a screw, screwed inside such an ankle, this for the attachment of such an object on the wall. A known device is described in FR 2 913039 .

Un tel dispositif présente, cependant, de nombreux inconvénients.Such a device has, however, many disadvantages.

En particulier, la mise en place d'une telle cheville nécessite, préalablement, le perçage du mur préfabriqué. Un tel perçage s'avère être une opération fastidieuse en raison du matériau et des armatures employés pour la réalisation de ce mur. De plus, un tel perçage implique une intervention en hauteur ce qui nécessite de recourir à un matériel approprié (par exemple une nacelle) et/ou de prendre des précautions particulières pour garantir la sécurité de l'opérateur en charge d'une telle opération.In particular, the establishment of such an ankle requires, beforehand, the drilling of the prefabricated wall. Such drilling proves to be a tedious operation because of the material and reinforcements used for the realization of this wall. In addition, such drilling involves intervention at height which requires the use of appropriate equipment (eg a nacelle) and / or take special precautions to ensure the safety of the operator in charge of such an operation.

De plus, l'immobilisation d'une telle cheville à l'intérieur du mur nécessite de recourir à des chevilles d'un type particulier, notamment à scellement chimique, dont le coût de revient est élevé.In addition, the immobilization of such an ankle inside the wall requires the use of pegs of a particular type, including chemical sealing, whose cost is high.

Lors d'une étape ultérieure de la construction du bâtiment, il convient de démonter le garde corps, ceci en retirant la vis du dispositif de fixation ce qui a pour effet de laisser apparents la cheville ainsi que l'orifice de réception de cette cheville, voire une partie du matériau ayant permis de sceller cette cheville. Il convient, alors, de faire disparaître les traces de la fixation du garde corps, ce qui implique une intervention supplémentaire (de bouchage de l'orifice) sur le mur préfabriqué, qui plus est réalisée en hauteur, ceci avec les inconvénients mentionnés ci-dessus.At a later stage of the construction of the building, it is advisable to dismount the guard, this by removing the screw of the fixing device which has the effect of leaving visible the peg and the receiving orifice of this peg, or a part of the material that has sealed this peg. It is advisable, then, to make disappear the traces of the fixing of the railings, which implies an additional intervention (of plugging of the orifice) on the prefabricated wall, which moreover is carried out in height, this with the drawbacks mentioned above. above.

La présente invention se veut de remédier aux inconvénients des dispositifs de l'état de la technique.The present invention is intended to overcome the disadvantages of devices of the state of the art.

A cet effet, l'invention concerne un dispositif de fixation selon la revendication 1.For this purpose, the invention relates to a fixing device according to claim 1.

On observera que les moyens pour fixer l'objet sur le mur préfabriqué comportent, avantageusement d'une part, une douille, d'autre part, une vis, comportant une tête pourvue d'une empreinte pour la réception d'un outil d'actionnement, et vissée à l'intérieur de la douille et, d'autre part encore, un capuchon, équipant la tête de la vis, et destiné à reposer dans le fond d'un moule pour la fabrication du mur préfabriqué.It will be observed that the means for fixing the object on the prefabricated wall comprise, advantageously on the one hand, a socket, on the other hand, a screw, comprising a head provided with an impression for the reception of a tool of actuation, and screwed inside the sleeve and, secondly, a cap, fitted to the head of the screw, and intended to rest in the bottom of a mold for the manufacture of the prefabricated wall.

De plus, le moyen pour positionner au moins un premier moyen pour fixer l'objet par rapport à au moins un deuxième moyen pour fixer cet objet est constitué par un support comportant au moins un premier moyen pour recevoir ce premier moyen pour fixer cet objet et au moins un deuxième moyen pour recevoir ce deuxième moyen pour fixer cet objet.In addition, the means for positioning at least one first means for fixing the object with respect to at least one second means for fixing this object is constituted by a support comprising at least a first means for receiving this first means for securing this object and at least a second means for receiving this second means for securing this object.

Une caractéristique additionnelle consiste en ce que le moyen pour placer les au moins deux moyens pour fixer l'objet sur le mur comporte au moins un élément, rendu solidaire du support, s'étendant à partir de ce support, et conçu pour venir prendre appui contre une paroi d'un moule pour la fabrication du mur préfabriqué. De plus, cet élément est constitué par une portion découpée d'une plaque plane qui, après découpage et retrait de cette portion découpée, constitue le support qui comporte au moins deux découpes chacune constituant au moins un moyen pour recevoir un moyen pour fixer l'objet.An additional feature is that the means for placing the at least two means for fixing the object on the wall comprises at least one element, made integral with the support, extending from this support, and designed to take support against a wall of a mold for the manufacture of the prefabricated wall. In addition, this element is constituted by a cut portion of a flat plate which, after cutting and removal of this cut portion, constitutes the support which comprises at least two cutouts each constituting at least one means for receiving a means for fixing the object.

L'invention concerne, également, un système de montage d'un garde corps sur un mur préfabriqué, ce système comportant un dispositif de fixation d'un objet selon l'une quelconque des revendications précédentes ainsi qu'un objet, d'une part, comportant au moins un moyen pour coopérer avec un des au moins deux moyens pour fixer cet objet sur le mur préfabriqué et que comporte le dispositif de fixation et, d'autre part, constitué par une platine, soit que comporte un garde corps, soit comportant un moyen pour recevoir un garde corps, soit comportant un élément pour recevoir un organe incorporant ou pourvu d'un moyen pour recevoir un tel garde corps.The invention also relates to a system for mounting a guardrail on a prefabricated wall, this system comprising an attachment device of an object according to any one of the preceding claims and an object, on the one hand , comprising at least one means for cooperating with one of the at least two means for fixing this object on the prefabricated wall and that comprises the fixing device and, secondly, constituted by a plate, or that includes a guard, or having means for receiving a guard, or having an element for receiving a member incorporating or provided with means for receiving such a guard.

Cette invention concerne, encore, un mur préfabriqué comportant au moins un dispositif de fixation présentant les caractéristiques mentionnées ci-dessus.This invention also relates to a prefabricated wall comprising at least one fixing device having the characteristics mentioned above.

La présente invention concerne, alors, un dispositif de fixation qui comporte au moins deux moyens pour fixer l'objet sur le mur préfabriqué ainsi qu'au moins un moyen pour placer les au moins deux moyens pour fixer, ceci à une distance déterminée de la tête du mur.The present invention relates, then, to a fastening device which comprises at least two means for fixing the object on the prefabricated wall and at least one means for placing the at least two means for fixing, this at a determined distance from the head of the wall.

La présence d'un tel moyen pour placer les au moins deux moyens pour fixer l'objet permet, avantageusement, de positionner de manière appropriée de tels moyens pour fixer par rapport au mur préfabriqué, ceci en sorte que, lors du montage du garde corps sur le mur, l'objet à fixer par l'intermédiaire de ces moyens pour fixer vienne se positionner immédiatement de manière appropriée par rapport à ce dispositif de fixation et par rapport au mur préfabriqué, plus particulièrement en sorte que le moyen (que comporte cet objet) pour coopérer avec un des moyens pour fixer cet objet soit positionné en parfaite correspondance avec un tel moyen pour fixer.The presence of such a means for placing the at least two means for fixing the object advantageously allows appropriate positioning of such means for fixing relative to the prefabricated wall, so that when mounting the guardrail on the wall, the object to be fixed through these means for to fix immediately position itself in a suitable manner with respect to this fixing device and with respect to the prefabricated wall, more particularly so that the means (that includes this object) to cooperate with one of the means for securing this object is positioned in perfect correspondence with such a way to fix.

La présence de deux moyens pour fixer l'objet sur le mur permet d'accroître la sécurité du dispositif de fixation et de réduire la dimension (plus particulièrement le diamètre) d'un tel moyen pour fixer, ceci par rapport à un dispositif de fixation comportant un unique moyen de fixation. Une telle réduction de dimension permet, alors, avantageusement, de réduire la dimension de la trace laissée par un moyen pour fixer un objet sur le mur préfabriqué, ceci au point d'éviter une intervention pour masquer une telle trace.The presence of two means for fixing the object on the wall makes it possible to increase the safety of the fixing device and to reduce the dimension (more particularly the diameter) of such means for fixing, this with respect to a fixing device having a single fastening means. Such a size reduction then makes it possible, advantageously, to reduce the size of the trace left by a means for fixing an object on the prefabricated wall, this to the point of avoiding intervention to hide such a trace.

Une autre caractéristique de l'invention consiste en ce que le moyen pour positionner au moins un premier moyen pour fixer l'objet par rapport à au moins un deuxième moyen pour fixer cet objet est constitué par un support comportant au moins un premier moyen pour recevoir ce premier moyen pour fixer cet objet et au moins un deuxième moyen pour recevoir ce deuxième moyen pour fixer cet objet. En fait, un tel moyen pour recevoir un moyen pour fixer l'objet est constitué par une découpe, que comporte le support, et dont la forme et/ou les dimensions sont définies pour recevoir un tel moyen pour fixer. De manière avantageuse, le moyen pour placer les au moins deux moyens pour fixer l'objet sur le mur comporte au moins un élément, rendu solidaire du support, et constitué par une portion découpée d'une plaque plane qui, après découpage et retrait de cette portion découpée, constitue le support et comporte deux découpes chacune constituant au moins un moyen pour recevoir au moins un moyen pour fixer l'objet.Another feature of the invention consists in that the means for positioning at least one first means for fixing the object with respect to at least one second means for fixing this object is constituted by a support comprising at least a first means for receiving this first means for fixing this object and at least a second means for receiving this second means for fixing this object. In fact, such a means for receiving a means for fixing the object is constituted by a cutout, that includes the support, and whose shape and / or dimensions are defined to receive such a means for fixing. Advantageously, the means for placing the at least two means for fixing the object on the wall comprises at least one element, made integral with the support, and constituted by a cut portion of a flat plate which, after cutting and removal of this cut portion, constitutes the support and comprises two cutouts each constituting the least means for receiving at least one means for securing the object.

Finalement, le système de montage selon l'invention permet, avantageusement, de monter un garde-corps en périphérie extérieure d'un mur préfabriqué ce qui autorise, avantageusement, la mise en oeuvre d'un mur sans avoir besoin de procéder au démontage des garde-corps et ainsi de profiter d'un protection permanente pendant toutes les phases constructives de montage des murs.Finally, the mounting system according to the invention advantageously makes it possible to mount a railing on the outer periphery of a prefabricated wall, which advantageously allows the use of a wall without the need to dismantle the walls. guardrail and thus to enjoy permanent protection during all the phases of construction of the walls.

La présente invention concerne le domaine du bâtiment et trouvera une utilité toute particulière lorsqu'il s'agit de fixer, de manière temporaire, un garde corps sur un mur préfabriqué.The present invention relates to the field of the building and will find a particular use when it is a question of fixing, temporarily, a railing on a prefabricated wall.

Cette invention concerne, alors, un dispositif de fixation 1 d'un objet 2 sur un mur préfabriqué 3 d'un bâtiment.This invention relates, then, a device 1 for fixing an object 2 on a prefabricated wall 3 of a building.

Un tel dispositif de fixation 1 est conçu pour être, au moins en partie, noyé à l'intérieur du matériau (plus particulièrement un liant hydraulique, notamment du béton) d'un tel mur préfabriqué 3.Such a fixing device 1 is designed to be at least partly embedded inside the material (more particularly a hydraulic binder, especially concrete) of such a prefabricated wall 3.

Selon l'invention, ce dispositif de fixation 1 comporte au moins deux moyens (10 ; 10') pour fixer ledit objet 2 sur le mur préfabriqué 3 ainsi qu'au moins un moyen 11 pour placer les moins deux tels moyens (10 ; 10') pour fixer l'objet 2 sur le mur préfabriqué 3, ceci à une distance déterminée de la tête 30 de ce mur 3.According to the invention, this fixing device 1 comprises at least two means (10; 10 ') for fixing said object 2 on the prefabricated wall 3 as well as at least one means 11 for placing the at least two such means (10; ') to fix the object 2 on the prefabricated wall 3, this at a determined distance from the head 30 of the wall 3.

A ce propos, on observera qu'un tel moyen (10 ; 10') pour fixer l'objet 2 sur le mur préfabriqué 3 comporte, d'une part, une douille 100, plus particulièrement une douille à plateau facilitant l'ancrage d'une telle douille à l'intérieur du matériau du mur préfabriqué 3. Tel qu'il sera décrit ci-dessous, une telle douille 100 présente, également, un collet 101 que comporte la paroi externe du corps de cette douille 100.In this regard, it will be observed that such a means (10; 10 ') for fixing the object 2 on the prefabricated wall 3 comprises, on the one hand, a bushing 100, more particularly a tray bushing facilitating the anchoring of Such a socket inside the prefabricated wall material 3. As will be described below, such a socket 100 also has a collar 101 that includes the outer wall of the body of this socket 100.

D'autre part, un tel moyen (10 ; 10') pour fixer comporte une vis 102, comportant une tête 103 pourvue d'une empreinte pour la réception d'un outil d'actionnement, et vissée à l'intérieur de la douille 100. Une telle vis 102 est, de préférence, constituée par une vis de type CHC comportant une tête 103 pourvue d'une empreinte à six pans creux.On the other hand, such a means (10; 10 ') for fixing comprises a screw 102, comprising a head 103 provided with an impression for the reception of an actuating tool, and screwed inside the socket 100. Such a screw 102 is preferably constituted by a CHC-type screw comprising a head 103 provided with an Allen key.

Selon une caractéristique additionnelle, une telle douille 100 et une telle vis 102 présentent un diamètre nominal compris entre 14 et 18mm, de préférence de l'ordre de 16mm.According to an additional characteristic, such a bushing 100 and such a screw 102 have a nominal diameter of between 14 and 18 mm, preferably of the order of 16 mm.

D'autre part encore, un tel moyen (10 ; 10') comporte un capuchon 104, équipant la tête 103 de la vis 102, et au moins en partie engagé (de préférence de manière serrée) à l'intérieur de l'empreinte que comporte la tête 103 de cette vis 102. En fait, ce capuchon 104 est destiné à venir reposer dans le fond (plus particulièrement contre la paroi du fond) d'un moule conçu pour assurer la fabrication du mur préfabriqué 3, ceci de sorte que, après démoulage du mur 3, ce capuchon 104 affleure à la surface du mur 3 et puisse être retiré de la tête 103 de la vis 102 afin de permettre la coopération de l'empreinte de cette tête 103 de vis 102 avec un outil d'actionnement.On the other hand, such a means (10; 10 ') comprises a cap 104, fitted to the head 103 of the screw 102, and at least partially engaged (preferably tightly) inside the footprint that includes the head 103 of the screw 102. In fact, this cap 104 is intended to rest in the bottom (particularly against the bottom wall) of a mold designed to ensure the manufacture of the prefabricated wall 3, so that that after demolding the wall 3, this cap 104 is flush with the surface wall 3 and can be removed from the head 103 of the screw 102 to allow the cooperation of the impression of the head 103 screw 102 with an actuating tool.

Une caractéristique additionnelle consiste en ce qu'un tel moyen (10 ; 10') pour fixer un objet 2 sur un mur préfabriqué 3 s'étend selon un axe qui est sensiblement perpendiculaire au plan selon lequel s'étend ce mur préfabriqué 3.An additional feature is that such means (10; 10 ') for fixing an object 2 to a prefabricated wall 3 extends along an axis which is substantially perpendicular to the plane along which this prefabricated wall 3 extends.

Le dispositif de fixation 1 comporte également un moyen 12 pour positionner au moins un moyen (10 ; 10') pour fixer l'objet 2, ceci par rapport à au moins un autre moyen (10' ; 10) pour fixer cet objet 2.The fixing device 1 also comprises a means 12 for positioning at least one means (10; 10 ') for fixing the object 2, with respect to at least one other means (10'; 10) for fixing the object 2.

A ce propos, on observera qu'un tel moyen 12 pour positionner est, plus particulièrement, conçu pour positionner au moins un moyen 10 pour fixer par rapport à au moins un autre moyen 10' pour fixer, ceci en sorte que l'entraxe de ces deux moyens (10 ; 10') pour fixer soit particulièrement précis.In this regard, it will be observed that such a means 12 for positioning is, more particularly, designed to position at least one means 10 for fixing relative to at least one other means 10 'to fix, so that the distance between these two means (10; 10 ') for fixing is particularly precise.

En fait, le moyen 12 pour positionner au moins un moyen 10 pour fixer l'objet 2 par rapport à au moins un autre moyen 10' pour fixer cet objet 2 est, plus particulièrement, conçu pour positionner au moins un premier moyen 10 pour fixer l'objet 2 par rapport à au moins un deuxième moyen 10' pour fixer cet objet 2.In fact, the means 12 for positioning at least one means 10 for fixing the object 2 relative to at least one other means 10 'for fixing the object 2 is, more particularly, designed to position at least a first means 10 for fixing the object 2 with respect to at least a second means 10 'for fixing this object 2.

Un tel moyen 12 pour positionner est, alors, constitué par un support 120 comportant au moins un premier moyen 121 pour recevoir ce premier moyen 10 pour fixer cet objet 2 et au moins un deuxième moyen 121' pour recevoir ce deuxième moyen 10' pour fixer cet objet 2.Such a means 12 for positioning is, then, constituted by a support 120 comprising at least a first means 121 for receiving this first means 10 for fixing the object 2 and at least a second means 121 'for receiving the second means 10' for fixing this object 2.

Selon un mode préféré de réalisation, le support 120 est constitué par une plaque plane, s'étend dans un plan perpendiculaire à l'axe d'extension d'au moins un moyen (10 ; 10') pour fixer l'objet 2. Une telle plaque plane est, de préférence, réalisée en un matériau métallique, plus particulièrement en tôle, dont l'épaisseur est comprise entre 1 et 5 mm, de préférence de l'ordre de 3mm.According to a preferred embodiment, the support 120 is constituted by a flat plate, extends in a plane perpendicular to the axis of extension of at least one means (10; 10 ') for fixing the object 2. Such a flat plate is preferably made of a metallic material, more particularly of sheet metal, the thickness of which is between 1 and 5 mm, preferably of the order of 3 mm.

En ce qui concerne les moyens (121 ; 121') pour recevoir les moyens (10 ; 10') pour fixer l'objet 2, ceux-ci (121 ; 121') sont constitués chacun par une découpe, que comporte le support 120, et dont la forme et/ou les dimensions sont définies pour recevoir un tel moyen (10 ; 10') pour fixer, ceci de manière traversante, voire de manière ajustée et serrée.With regard to the means (121; 121 ') for receiving the means (10; 10') for fixing the object 2, these (121; 121 ') each consist of a cutout, which comprises the support 120 , and whose shape and / or dimensions are defined to receive such means (10; 10 ') for fixing, this in a through manner, or even in a tight and tight manner.

Le support 120 comporte alors deux découpes, chacune constituant un moyen (121 ; 121') pour recevoir un tel moyen (10 ; 10') pour fixer un objet 2.The support 120 then comprises two cutouts, each constituting a means (121; 121 ') for receiving such means (10; 10') for fixing an object 2.

Selon un mode préféré de réalisation, un tel support 120 comporte, alors, également, un moyen 122 pour raccorder ces deux découpes. Un tel moyen 122 pour raccorder est, là encore, constitué par une découpe que comporte le support 120.According to a preferred embodiment, such a support 120 also includes a means 122 for connecting these two cutouts. Such means 122 for connecting is, again, constituted by a blank that includes the support 120.

Tel que visible sur les figures en annexe, les découpes (définissant les moyens 121 ; 121' pour recevoir un moyen 10 ; 10' pour fixer et le moyen 122 pour raccorder ces moyens 121 ; 121' pour recevoir) peuvent être réalisées au moyen d'un laser.As can be seen in the appended figures, the cutouts (defining the means 121; 121 'for receiving a means 10; 10' for fixing and the means 122 for connecting these means 121; 121 'for receiving) can be realized by means of a laser.

On observera que ces découpes peuvent être réalisées dans une plaque plane telle que susmentionnée et en sorte de définir, au sein de cette plaque plane, le support 120 ainsi qu'un unique élément 110, résultant du découpage de cette plaque plane, constitué par une portion découpée de cette plaque plane, et qui, après avoir été retiré de cette plaque plane, est susceptible d'être utilisé pour la fabrication du dispositif de fixation 1 comme il sera décrit plus en détail ci-dessous.It will be observed that these cuts can be made in a flat plate as mentioned above and so as to define, within this flat plate, the support 120 and a single element 110, resulting from the cutting of this flat plate, constituted by a cut portion of this flat plate, and which, after being removed from this flat plate, is may be used for the manufacture of the fastening device 1 as will be described in more detail below.

Tel que mentionné ci-dessus, les moyens (10 ; 10') pour fixer un objet 2 comportent une douille 100 présentant un collet 101. Aussi et selon une caractéristique additionnelle de l'invention, , les dimensions des découpes, que comportent le support 120, constituant les moyens (121 ; 121') pour recevoir les moyens (10 ; 10') pour fixer l'objet 2, et qui sont traversées par ces moyens (10 ; 10') pour fixer l'objet 2, sont définies pour que ce support 120 prenne appui contre le collet 101 de ces moyen (10 ; 10') pour fixer l'objet 2.As mentioned above, the means (10; 10 ') for fixing an object 2 comprise a sleeve 100 having a collar 101. Also and according to an additional feature of the invention, the dimensions of the cuts, which comprise the support 120, constituting the means (121; 121 ') for receiving the means (10; 10') for fixing the object 2, and which are traversed by these means (10; 10 ') for fixing the object 2, are defined so that this support 120 bears against the collar 101 of these means (10; 10 ') to fix the object 2.

Tel que mentionné ci-dessus, le dispositif de fixation 1 selon l'invention comporte un moyen 11 pour placer les au moins deux moyens (10 ; 10') pour fixer l'objet 2 sur le mur préfabriqué 3, ceci à une distance déterminée de la tête 30 de mur 3.As mentioned above, the fixing device 1 according to the invention comprises a means 11 for placing the at least two means (10; 10 ') for fixing the object 2 on the prefabricated wall 3, this at a determined distance of the wall head 3.

En fait, ce moyen 11 pour placer comporte au moins un élément 110, rendu solidaire du support 120, s'étendant à partir de ce support 120 et conçu pour venir prendre appui contre une paroi d'un moule conçu pour la fabrication du mur 3, plus particulièrement contre la paroi d'un tel moule délimitant la tête 30 du mur 3.In fact, this means 11 for placing comprises at least one element 110, made integral with the support 120, extending from the support 120 and designed to bear against a wall of a mold designed for the manufacture of the wall 3 , more particularly against the wall of such a mold delimiting the head 30 of the wall 3.

On observera que cet élément 110 présente une extrémité libre de forme arrondie destinée à venir en butée contre la paroi du moule. En fait, le caractère arrondi de cette extrémité libre permet, avantageusement, de minimiser l'impact de cet élément 110 sur la tranche 31 du mur 3.It will be observed that this element 110 has a free end of rounded shape intended to abut against the wall of the mold. In fact, the rounded nature of this free end advantageously makes it possible to minimize the impact of this element 110 on the edge 31 of the wall 3.

Tel que mentionné ci-dessus, cet élément 110 est rendu solidaire du support 120 ce qui est réalisé, de préférence, par soudure.As mentioned above, this element 110 is made integral with the support 120 which is made preferably by welding.

De plus, cet élément 110 est rendu solidaire de ce support 120, ceci en sorte que cet élément 110 s'étende perpendiculairement à la direction d'extension de ce support 120 et/ou parallèlement au plan dans lequel s'étend ce support 120 et/ou perpendiculairement à l'axe d'extension des moyens (10 ; 10') pour fixer l'objet 2 et/ou en formant un angle (notamment droit) avec une droite passant par les axes d'extension de ces moyens (10 ; 10') pour fixer l'objet 2.In addition, this element 110 is secured to this support 120, so that this element 110 extends perpendicularly to the direction of extension of the support 120 and / or parallel to the plane in which the support 120 extends and or perpendicular to the axis of extension of the means (10; 10 ') for fixing the object 2 and / or forming an angle (in particular right) with a straight line passing through the extension axes of these means (10; 10 ') to fix the object 2.

En fait et tel que mentionné ci-dessus, cet élément 110 est, de préférence, constitué par une portion découpée d'une plaque plane qui, après découpage et retrait de cette portion découpée, constitue le support 120 qui comporte au moins une découpe constituant au moins un moyen (121 ; 121') pour recevoir un moyen (10 ; 10') pour fixer l'objet 2.In fact and as mentioned above, this element 110 is preferably constituted by a cut portion of a flat plate which, after cutting and removal of this cut portion, constitutes the support 120 which comprises at least one cutout constituting at least one means (121; 121 ') for receiving a means (10; 10') for securing the object 2.

Tel que mentionné ci-dessus, le dispositif de fixation 1 comporte au moins deux moyens (10 ; 10') pour fixer un objet 2 sur un mur préfabriqué 3. Un tel moyen (10 ; 10') comporte un capuchon 104 destiné à reposer dans le fond d'un moule conçu pour réaliser un tel mur 3. Ce dispositif de fixation 1 comporte, également, un moyen 11 pour placer au moins les moyens (10 ; 10') pour fixer ledit objet 2, ceci à une distance déterminée de la tête 30 de mur 3.As mentioned above, the fixing device 1 comprises at least two means (10; 10 ') for fixing an object 2 to a prefabricated wall 3. Such means (10; 10') comprises a cap 104 intended to rest in the bottom of a mold designed to produce such a wall 3. This fixing device 1 also comprises a means 11 for placing at least the means (10; 10 ') for fixing said object 2, this at a determined distance of the wall head 3.

Selon un mode de réalisation préféré de l'invention, ce dispositif de fixation 1 comporte, alors, également, un moyen 13 pour stabiliser le dispositif de fixation 1 et équipant le moyen 11 pour placer, à une distance déterminée de la tête 30 de mur 3, les au moins deux moyens (10 ; 10') pour fixer l'objet 2 sur le mur 3.According to a preferred embodiment of the invention, this fastening device 1 also comprises a means 13 for stabilizing the fastening device 1 and equipping the means 11 to place, at a determined distance from the wall head 30 3, the at least two means (10; 10 ') for fixing the object 2 on the wall 3.

En fait, ce moyen pour stabiliser 13, d'une part, est conçu pour reposer dans le fond du moule, ceci à l'instar du capuchon 104 des moyens (10 ; 10') pour fixer l'objet 2 et, d'autre part, constitue un pied au travers duquel le dispositif de fixation 1 repose dans le fond de ce moule, ceci à l'instar de ces moyens (10 ; 10') pour fixer l'objet 2.In fact, this means for stabilizing 13, on the one hand, is designed to rest in the bottom of the mold, this like the cap 104 means (10; 10 ') for fixing the object 2 and, d' on the other hand, constitutes a foot through which the fixing device 1 rests in the bottom of this mold, just like these means (10; 10 ') for fixing the object 2.

Tel que visible sur les figures en annexe, le moyen 13 pour stabiliser équipe le moyen 11 pour placer, ceci à proximité de l'extrémité libre de ce moyen 11 pour placer.As can be seen in the appended figures, the means 13 for stabilizing equips the means 11 to place, this close to the free end of this means 11 to place.

Un mode préféré de réalisation consiste en ce que ce moyen 13 pour stabiliser est constitué par une cale de Filzmoser.A preferred embodiment is that this means 13 for stabilizing is constituted by a wedge of Filzmoser.

Tel que mentionné ci-dessus, le dispositif de fixation 1 est conçu pour être au moins en partie noyé à l'intérieur du matériau du mur préfabriqué 3. A ce propos, on observera que, selon un mode de réalisation préféré de l'invention, le moyen 11 pour placer les au moins deux moyens (10 ; 10') pour fixer l'objet 2, le moyen 12 pour positionner au moins un tel moyen (10 ; 10') pour fixer l'objet 2 par rapport à au moins un autre moyen (10' ; 10) pour fixer cet objet 2 et le moyen 13 pour stabiliser le dispositif de fixation 1 sont intégralement noyés à l'intérieur du matériau du mur 3. En ce qui concerne les moyens (10 ; 10') pour fixer ledit objet 2, ceux-ci comportent, d'une part, une douille 100 et une vis 102 intégralement noyées à l'intérieur du matériau du mur 3 et, d'autre part, un capuchon 104, uniquement partiellement noyé à l'intérieur du matériau du mur 3, et affleurant à la surface de ce mur 3, ceci en sorte de pouvoir être retiré après la fabrication du mur 3 afin d'accéder à la vis 102 dans le but de visser celle-ci 102 hors de sa douille 100 avant de la revisser dans cette douille 100 pour assurer la fixation de l'objet 2.As mentioned above, the fixing device 1 is designed to be at least partly embedded inside the material of the prefabricated wall 3. In this regard, it will be observed that, according to a preferred embodiment of the invention, the means 11 for placing the at least two means (10; 10 ') for fixing the object 2, the means 12 for positioning at least one such means (10; 10') to fix the object 2 with respect to at least one other means (10 '; 10) for fixing this object 2 and the means 13 for stabilizing the fixing device 1 are integrally embedded inside the material of the wall 3. as regards the means (10; 10 ') for fixing said object 2, these comprise, on the one hand, a bushing 100 and a screw 102 integrally embedded inside the material of the wall 3 and, on the other hand, part, a cap 104, only partially embedded inside the material of the wall 3, and flush with the surface of the wall 3, so that it can be removed after the manufacture of the wall 3 to access the screw 102 in order to screw the latter 102 out of its socket 100 before screwing it back into this socket 100 to secure the object 2.

Tel que mentionné ci-dessus, la présente invention concerne un dispositif de fixation 1 d'un objet 2 sur un mur préfabriqué 3 d'un bâtiment.As mentioned above, the present invention relates to a device 1 for fastening an object 2 to a prefabricated wall 3 of a building.

A ce propos, on observera que cette invention trouvera une application particulièrement appropriée lorsqu'il s'agit de monter, de manière temporaire, un garde corps sur un tel mur préfabriqué 3.In this regard, it will be observed that this invention will find a particularly suitable application when it comes to temporarily mount a guard on such a prefabricated wall 3.

La présente invention concerne, alors également, un système 4 de montage d'un tel garde corps sur un mur préfabriqué 3.The present invention also relates to a system 4 for mounting such a guard on a prefabricated wall 3.

Un tel système 4 de montage comporte, alors, un dispositif de fixation 1 présentant les caractéristiques mentionnées ci-dessus.Such a mounting system 4 then comprises a fixing device 1 having the characteristics mentioned above.
